The MK1 MOD 1-M line, revamped for 2018, features the PWS long stroke
piston system. Internally, this line offers the tried and true system
that PWS owners have grown to know and love. Featuring a free-float MLOK
handguard, forward assist controls, and a more true to mil-spec design,
the MK1 MOD 1-M line is a go-to for not only civilians, but also Law
Enforcement. With fully forged receivers, the MK1 MOD 1-M is a
no-nonsense tool for when you need a high value option that is
relentless and unstoppable.
